FBI Director James Comey’s letter notifying Republican leaders that there might — just might — be more Hillary Clinton emails to investigate 11 days before the presidential election was unprofessional, irresponsible and possibly a violation of federal ethics laws.

Whatever the man was thinking, whatever his motivation, he has destroyed his own credibility and the appearance if not the reality of FBI neutrality in politics. After this awkward, inscrutable intrusion into a presidential race, against the advice of the Justice Department, how can he continue in office?

He should not. Although if Donald Trump becomes president thanks to this intervention, you can bet he’ll name Comey the FBI’s J. Edgar Hoover Director for Life.

The question now is what this does to the election less than a week away. Revelations about both candidates flow fast and furious, but the polls are moving away from Clinton and toward Trump.

On top of Comey’s inscrutable notification, we also have Wikileaks, the conscience-free purveyor of private emails, which is posting messages that federal officials say were gathered by Russian hackers apparently out to help Trump. The emails are embarrassing for sure — but so are Trump’s sexist 3 a.m. Tweets, and he discloses them on purpose.

Now The New York Times and The Washington Post are delving into Trump’s tax strategies, which are of dubious legality — apparently implemented against legal advice — and his false claims of philanthropy. This doesn’t seem to grab the national psyche like emails, but it should. Anybody who wants to see Clinton’s emails should be demanding to see Trump’s tax returns as well.

The odds are slim that new emails will change the FBI’s conclusion that Clinton did not show intent to expose secret information, which Comey said was the reason for not prosecuting her. Trump’s tax problems and new accusations from women are likely to outlast the email controversy, regardless of who becomes president. But that is cold comfort less than a week before the election.

There is no question who should be president. Trump’s moral compass, unstable demeanor and disdain for American values of civility and due process make him not only unfit but dangerous. Clinton is eminently qualified. She made stupid mistakes and should have known better, but Trump’s liabilities are deliberate, and he’s proud of them.

The irony of the Comey disaster is that it goes back to a stupid mistake by Bill Clinton and Attorney General Loretta Lynch. It was his stroll across the tarmac last summer to visit her in her private plane, and her willingness to chat, that compromised her ability to maintain jurisdiction over the email case. She delegated the decision on whether to prosecute to Comey and the FBI, which is supposed to be the investigative arm.
